Abstract:
Compared with Si-IGBT, there is no conductance modulation effect in SiC-MOSFET which makes it a higher conduction loss. However, SiC-MOSFET can be operated in higher frequency on account of its low switching loss. Based on this method, Hybrid Switch (HyS) combines both advantages of Si-IGBT and SiC-MOSFET, and the cost is closer to Si IGBT. In this paper, a 1200V/400A HYS with Si-IGBT and SiC-MOSFET is fabricated and tested under Double-Pulse Test (DPT). Also, a gate driver circuit with Miller Clamp is designed and applied for 1200V/400A HyS.
